having devoted 80 years to keeping the troublesome roof repaired. In 1987 the museum building was almost entirely demolished, retaining just the classical portico. In its place, and built of glass, steel and concrete, is the new and significantly expanded National Roman Legion Museum. In 2018 the building had to close for 13 months while essential roof repairs were carried out. Post-war archaeology The 1970s saw a new wave of archaeological activity, culminating in the 1977 to 1981 excavation of the fortress baths by J. David Zienkiewicz. It is believed that the baths complex was the only stone-built building in the new fortress of 75 AD, which was otherwise timber-built initially. Although initially a rescue dig, significant parts of the Baths site were preserved in situ, and were first opened to the public in 1980 in the care of Cadw as a public archaeological attraction. In the years 1984-90 the focus shifted outside the walls of the fortress to excavate areas of the canabae, the civil settlement that had grown up around the fortress. There had long been an awareness of extramural buildings, and some of the earliest excavations had looked at the medieval castle site, near the south-east gates. Property developments at an extensive site alongside Mill Street, on the north-east side of the fortress, provided an opportunity for more up to date archaeological methods to investigate the area and consider the status of the canabae as a whole. Led by Edith Evans, it demonstrated that the civil settlement was more extensive and varied than once thought. With the nearby town of Caerwent, plus civil settlements at Usk and Bulmore it was part of a settled romanised landscape, and over several centuries became a substantial garrison town. It was not promoted to regional capital status, as happened at York, but from the limited evidence available at both British and other examples, Caerleon's civil settlement in the 2nd and 3rd centuries would have looked recognisably comparable to most such fortress canabae. In a long-established chronology for the fortress it was assumed the military had departed by the end of the third century. Mounting evidence of fourth century occupation was considered by Edith Evans in a wide-ranging review of 2004. She suggested a case for a reformed and reduced legionary presence into the fourth century, but stressed that the three options (Smaller fort, Smaller garrison or Civilian use only) were all
